The last few months of his life were apparently the best times of his life, also with amount of heroin he took plus the other drug found with it to make it more potent, he would never have thought about suicide due to the fact that he would have been having the best feeling in the world, even if you were suicidal at the moment you wouldnt want to kill yourself when you were that high you would be in heaven. also his credit card was being used AFTER. He also wansnt labeled suicidal until after his death when Courtney said that he was. He probably didnt kill himself, look at the information about surrounding the case.
